Physical/Chemical Properties and Changes

Physical Property

A property of matter that can be seen or measured without changing the substance into something else.

List of Physical Properties

Color, shape, texture, luster, mass, weight, volume, density, state, flexibility, magnetism, conductivity, malleability, ductility, and solubility.

Flexibility

The ability to be stretched or bent.

Magnetism

The ability to attract things like a magnet.

Conductivity

The ability to conduct electricity.

Malleability

The ability to be shaped when hit with a hammer.

Ductility

The ability to be stretched into a string.

Solubility

The ability to dissolve in water.

Chemical Property

A property of matter that tells how the substance can form new substances when it reacts with something else.

List of Chemical Properties

Rust, flammability, and reactivity.

Rust

When oxygen and iron combined, this new substance is formed.

Flammability

The ability to burn.

Reactivity

When two chemicals mix to form another chemical.

Physical Change

A change in which the appearance changes but it is still the same substance.

Chemical Change

A change in which a substance becomes a new substance that has different properties.

Chemical

Chemical

What kind of change is happening when iron rusts?

Chemical

What kind of change is wood burning?

Physical
